He was born in Highfield, near Doncaster, in September 1935, one of three children born to miner William Pegg and his wife Jessie. His father also played amateur football to a high standard during the 1930s, winning a number of trophies with local football teams.

He was the club's first-choice outside left until the final few months before the disaster (when he was displaced by Albert Scanlon) and had collected two League Championship winner's medals in the two seasons leading up to the Munich air disaster.

He was tipped by many to succeed the ageing Tom Finney in the England team. Still only 22 years old when he died, he was one of the youngest people to die out of the 23 who lost their lives at Munich.

He was born in the village of Highfields, north of Doncaster and he was buried in the nearby Redhouse Cemetery. A memorial chair was dedicated in his memory at St. George's Church in Highfields and when that church was closed the chair was moved to All Saints' Church in Woodlands which now serves both villages.

Pegg's sister, Mrs Irene Beevors, contributed to a 1998 ITV documentary, Munich: End of a Dream, which commemorated the 40th anniversary of the tragedy. She, Pegg's brother and Pegg's other sister, Mrs Doreen Robinson (who now lives in Australia) visited the scene of the Munich air crash in September 2005, on what would have been his 70th birthday, to pay tribute to their brother.[1]

He was also outlived by both of his parents, though they have both since died; his father in May 1980 and his mother in August 2006. They are both buried alongside him.[2]

More than 50 years after his death, Pegg was portrayed by actor Brogan West in a BBC film, United, which was centred on the Munich air disaster.[3]
